Input File Specification for Face Liveness Detection
Image Specification
- The input image should be a frontal selfie.
frontal selfie
- All atribute on the image is calculated on the passive liveness check. Please input the original image without any cropping and without any enhancement on the camera filter or photoshopped, because we need more context on passive liveness evaluation.
- The liveness detection works best in such environments:
- On a uniform background
- Good image quality such as: not dark, sharp or not blurred, has sufficient contrast, not overshadowed, no spotlight present on the face.
- No wearables occluded the face
